  • the insulating bushing is tubular and has inside an electrical conductor of a smaller diameter than the inside diameter of the bushing. At its ends, the gap between the bushing and the conductor is hermetically sealed, so that there is a relatively great clearance between the bushing and the conductor. In the bushing there is a bore.
  • the flange is of a two-part design, so that between the flanges there is a clearance, which connects the clearance in the bushing to the clearance between the flanges through the bore in the bushing, or a one-part flange is provided with a bore that corresponds to the bore of the bushing.

  • the material of the bushing is a ceramic, which is known as being a brittle material.
  • the bushing may rupture under mechanical loading, especially since it protrudes beyond the surface of the flange. In the event of rupture, the barrier between the safety enclosure and the surroundings would be breached.

  • the electrical conductor is in this case formed by a copper rod which is surrounded by a steel tube that establishes the connection with the glass material of the insulation component.
  • the sealing of the connection of the copper rod to the steel tube must be ensured.
  • Such a solution is mechanically stable, but requires increased production expenditure, in particular on account of the required connection of the copper rod and the steel tube.
  • the object of the invention is to provide an electrical feed-through that is suitable for high current intensities, is able to withstand high mechanical loads and can be produced with reduced expenditure.
  • the feed-through comprises a flange, which has an upper side and an underside, and a through-opening with an inner wall and also a conductor for electric current, which is arranged within the through-opening by means of at least one electrically insulating insulation component and in this way is connected to the flange by means of the insulation component.
  • the through-opening is sealed off.
  • the through-opening extends from the upper side to the underside of the flange. Since the terms upper side and underside are relative terms, the through-opening similarly extends from the underside to the upper side of the flange.
  • the side facing the interior of the safety enclosure is referred to as the upper side; the underside is that side of the surface of the flange that is opposite from the upper side.
  • the at least one insulation component is provided in the through-opening in such a way that it is flush with the upper side and/or the underside of the flange. This means that it does not protrude beyond the upper side and/or the underside of the flange.
  • the at least one insulation component is provided such that it is set back from the upper side and/or the underside of the flange in the through-opening.

  • the conductor for electric current consists at least in its core region of a cobalt-iron alloy, the cobalt content of which is from 68% by weight to 84% by weight.
  • the iron content is accordingly in particular from 16% by weight to 32% by weight. It is similarly possible that small fractions of other substances, in particular metals, are contained in the alloy, the proportion of which can be at most approximately 2% by weight.

  • the corresponding iron contents are logically obtained mathematically.
  • the stated alloy with the stated contents of its components on the one hand has good electrical properties, in particular with respect to conductivity, but on the other hand can also be connected well to glass as the material of the insulation component, in particular because the chemical properties are compatible and the coefficients of thermal expansion ⁇ 20-300 of the stated cobalt-iron alloy are suitable for the glass materials stated further below.
  • the stated cobalt-iron alloy may have coefficients of thermal expansion ⁇ 20-300 in the temperature range around 100° C. of approximately 9.0 ppm/K to approximately 12 ppm/K; values of approximately 9.5 ppm/K to approximately 11.5 ppm/K are particularly advantageous.
  • coefficient of thermal expansion is generally known. As used in the present description, this term represents more precisely the coefficient of linear thermal expansion, commonly represented by the symbol ⁇ . As used in the present description, the term coefficient of thermal expansion even more precisely is meant to shortly name the coefficient ⁇ 20-300 , which is commonly used to represent the average linear coefficient of thermal expansion in the temperature range from 20° C. to 300° C., shortly symbolized by ⁇ 20-300 .

  • Such small values of the specific electric resistance in particular enables the inventive feedthrough to connect devices with high electric currents without heating the conductor to a larger amount.
  • the inventive feed-through is suitable for low temperature applications because the cooled media are not heated by the conductor when the device is under operation. Furthermore, the balance between the coefficient of thermal expansion of the flange, the conductor and the insulation-component is not disturbed.
  • the material of the insulation component may be chosen such that it has a coefficient of thermal expansion in the temperature interval of the planned operating conditions that is less than that of the flange and/or of the stated cobalt-iron alloy.

  • the balance of the coefficients of thermal expansion of the materials of the flange, the insulation component and/or insulation components and of the conductor is of particular importance, because otherwise at the operational temperature, especially changing operational temperatures, a permanently hermetical or at least tight feed-through element could not be achieved.
